Bolt.new Mobile App: Can It Build for iOS and Android?

Yes, Bolt.new can build a mobile app. Since its V2 release it generates React Native code through an official Expo integration, so you can describe an iPhone or Android app in plain English and get working cross-platform code, even from a Windows machine. The important catch is what happens next: Bolt runs entirely in your browser, so it produces the code but cannot build the signed app or ship it to the App Store. That final step is manual, using Expo’s build service and your own developer accounts. Bolt is excellent for generating and prototyping a mobile app fast, and the cleanest way to make it look good is to start from a VP0 design and hand it to Bolt.

Can Bolt.new build a mobile app?

The short answer is yes, with an asterisk. Bolt.new began as a web app builder, but its V2 update added React Native and Expo support, which lets it generate real mobile app code for iOS and Android from a single prompt. When you ask Bolt for a mobile app, it automatically reaches for Expo, the most popular React Native toolchain, so the same codebase targets both platforms.

What Bolt gives you is genuine, editable React Native code, not a locked no-code project. You can prototype a full app, refine it by chatting, and preview it, all in the browser. The asterisk is that generating the code and shipping a store-ready app are two different jobs, and Bolt only does the first.

How Bolt.new builds mobile apps with Expo

Bolt’s mobile support rests on its Expo partnership. Expo lets you build for iPhone and Android from one codebase, and it removes the traditional need for a Mac to start, so you can even generate an iPhone app from Windows. According to Bolt’s own Expo documentation, when you request a mobile app the platform scaffolds an Expo project and generates the screens and navigation for you.

In practice the workflow feels like Bolt’s web experience. You describe the app, Bolt generates it, and you iterate through chat. You can preview the app in the browser and on your phone through the Expo Go app, which is what makes the loop fast. For getting from idea to a working prototype, this is genuinely quick.

What “native” really means here

Before you commit, it helps to understand what you are building. React Native with Expo does not produce a traditional native app. You are building a JavaScript app that renders using native components, which is a real app, but not the same as hand-written Swift or Kotlin.

For most apps, social, commerce, content, tracking, this distinction does not matter, and the result feels native to users. It starts to matter for graphics-intensive apps, like 3D games, and for features that need deep device access. As independent reviews of Bolt for mobile note, the Expo approach covers the large majority of app ideas but is not the tool for a performance-critical or hardware-heavy product.

What you can and cannot build with Bolt mobile

It helps to be realistic about scope before you start. Bolt’s Expo output suits the large category of standard apps: content feeds, social features, booking and scheduling, trackers, simple commerce, dashboards, and utility tools. For these, the React Native result is fast to build and feels native to users.

Where it struggles is the same place React Native itself does. Graphics-intensive apps like 3D games, apps that lean on augmented reality or LiDAR, and features that need deep, platform-specific hardware access are a poor fit. Bolt also focuses on generating the app, not on complex backend architecture, so a data-heavy product may need a separate backend, and a Bolt alternative for complex backends is worth a look if that is your case. Match your idea to this scope and Bolt will feel powerful rather than limiting.

The deployment gap you need to plan for

Here is the limitation that surprises people most. Bolt runs in WebContainers, browser-based virtual machines, which cannot run Xcode, Android Studio, or Expo’s build pipeline. So Bolt generates your React Native code, but it cannot produce the signed binary that the App Store requires.

That means deployment is entirely manual. As the community docs on Expo mobile apps explain, you export the code, then use Expo Application Services, known as EAS, to run the actual build, configure signing certificates, and submit to the stores yourself. Bolt provides no help with app signing, developer accounts, or submission. Knowing this up front is the difference between a smooth launch and a frustrating surprise at the finish line, and it is worth reading the export to App Store fixes before you start.

Should you build mobile at all with Bolt?

Because Bolt started on the web, it is worth asking whether your idea even needs a native app. A responsive web app, which Bolt builds effortlessly, can be shared with a link, needs no store review, and reaches users on any device instantly. For validating an idea, that is often the faster path.

Go mobile when the app genuinely benefits from being installed: push notifications, offline use, a home-screen presence, or camera and sensor access. If those are core to the product, Bolt’s Expo route gives you a real mobile app. If they are not, shipping the web version first and adding a native app later is usually the cheaper, faster way to learn whether people want the product at all, and it saves you the manual build pipeline until you know you need it.

Bolt.new mobile vs dedicated mobile builders

Bolt is one option among several, and it sits at the code-generation end of the spectrum. Others handle more of the build and publish path:

Builder	Mobile output	Runs the build	Path to store	Best for
Bolt.new	React Native via Expo	No, browser only	Manual, EAS and submit yourself	Fast prototyping, web plus mobile
Rork	React Native, native Swift option	Yes, built in	Assisted publishing	Native mobile depth
a0.dev	React Native	Yes	One-click to stores	Fastest path to the App Store
CatDoes	No-code native	Yes	Ships to the stores	No-code native mobile

If you want the app in the stores with the least friction, a dedicated mobile builder like a0.dev or CatDoes does more for you, a tradeoff compared head to head in a0.dev vs Rork. If you value Bolt’s speed and want the code, Bolt plus manual EAS is a fine path.

What it costs to ship a Bolt.new mobile app

The costs come in two parts. First, Bolt’s own subscription, which starts free with a paid plan for more usage. Second, the platform fees that any mobile app requires: an Apple Developer account at $99 per year and a Google Play developer account at a one-time $25. These are Apple and Google’s fees, not Bolt’s, and you pay them regardless of how the app was built.

Because Bolt meters usage with tokens, heavy iteration can add up, so it is worth understanding its pricing before you dive in. Budget for the subscription and the store fees together, and remember that EAS itself has a free tier that covers occasional builds.

When Bolt.new is the right choice for mobile

Bolt shines when speed and code ownership matter more than a hand-held path to the stores. It is a strong choice if you want to prototype a mobile app quickly, if you are comfortable running an EAS build once the code is ready, or if you are already using Bolt for a web app and want a mobile companion in the same tool.

It is the wrong choice if you want a no-code experience that publishes for you, if your app is graphics-heavy or needs deep native hardware features, or if the manual EAS and submission steps feel like a wall rather than a speed bump. In those cases, a builder that owns the whole pipeline, or the native depth of Rork, will serve you better.

From Bolt code to the App Store, step by step

Getting a Bolt mobile app live follows a clear sequence:

1. Generate and refine the app in Bolt until the core flow works.
2. Export the code to your own repository so you own it.
3. Set up EAS with the Expo command line on your machine.
4. Configure signing, your Apple certificates and Android keystore.
5. Run the EAS build to produce the signed iOS and Android binaries.
6. Create developer accounts, Apple at $99 per year and Google at $25 once.
7. Submit to the App Store and Google Play, and handle review.

None of these steps are exotic, but they are on you, and the React Router and Expo mobile fixes are worth bookmarking for the common snags.

Common Bolt.new mobile problems and fixes

A few issues come up often enough to expect them. The Expo preview can behave differently from the final build, so test on a real device early rather than trusting the browser preview alone. Navigation is a frequent snag, since React Native routing differs from the web, and mismatches often produce blank screens that look like a crash but are really a routing problem.

The EAS build step is where most people stumble, because signing certificates and configuration are unforgiving of small mistakes. Work through them methodically, and keep the iOS simulator black screen fix handy, since a blank simulator is a common early symptom rather than a real failure. None of these are dealbreakers, but they are the reason to budget time for a build-and-test phase instead of assuming the app is done the moment the code looks right.

Making a Bolt.new mobile app look good

Bolt generates whatever the prompt describes, so a vague request yields a generic, cluttered app. Because the look is the first thing users judge, that is worth solving before you build.

VP0 is a free iOS design library for people building apps with AI, and each design has a machine readable source page. You paste the link into Bolt, and it generates the mobile app around a clean, considered design instead of a default template. For the cost of nothing, your Bolt app looks intentional, which matters as much for a prototype you are showing investors as for a finished product.

Tips for a better Bolt.new mobile build

A few habits make the Bolt mobile experience much smoother. Be specific in prompts about the platform and the screens, since a clear request produces cleaner React Native than a vague one. Build and refine one screen at a time rather than asking for the whole app at once, which keeps the code manageable and easier to debug. Give Bolt a real design reference so the result is not generic. Preview on your actual phone through Expo Go from the start, not just in the browser, so you catch platform differences early. And export your code to your own repository early, so you own the project and can run EAS builds without depending on the browser session. Small as they are, these habits are the difference between a smooth prototype and a tangled one.

Key takeaways: building a mobile app with Bolt.new

Bolt.new can build a mobile app: its Expo integration generates real React Native code for iOS and Android from a prompt, even on Windows. The limit is that Bolt runs in the browser, so it stops at code and leaves the signed build and store submission to you, via Expo’s EAS and your own Apple and Google accounts. Budget the $99 per year Apple fee and the $25 Google fee, and pick Bolt when you value speed and owning the code over a hand-held publish. Start from a clean VP0 design so the app looks intentional, and expect to run the final build yourself.
